> We still recommend using the bare disk method. Because Doris itself already has multiple copies, using Raid will cause unnecessary storage waste. In addition, the raid itself will also depend on specific hardware conditions raid可以用软件raid，冗余还好。 想问一下，如果我在be上配置了多个磁盘，be在往磁盘写数据的时候，是顺序往各个磁盘上写吗？ 如果是这样，那我直接用软件raid盘，io性能可以提升好几倍？ 我们在使用clickhouse的时候就是这样的，raid 让io吞吐提升好几倍。 ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
